Odd. Can you ignore the animate tool and replot the particle tracks at a later time? In the File>Preferences find and turn on Titles. That adds a couple of lines of text at the bottom of the image which includes the solver time.
If you plot a couple of contours of velocity on the model at a later time how does it look? Use isosurfaces/planes (both work, I just prefer the former) to show what's happening inside the domain.
